木工平压刨机床是木工生产中不可缺少的设备.由于结构简单、制造与使用方便、生产效率也高,所以在现代工矿企业中被广泛利用.木工平压刨机床(以下简称木平刨)是由电动机、刀轴、平台等组成,设备运行时靠电动机带动刀轴旋转而进行刨削木料.设备开动后主轴转数达2900转/分,刀轴转数达4800转/分.同时它与静止的平台面板间隙气流相互作用,引起空气气流扰动,形成共鸣器(俗称风胡芦),即产生空气动力性噪声,这时的空载噪声高达103分贝(A).当进行切
Woodworking planer planing machine is an indispensable equipment in the production of woodworking.With the simple structure, convenient manufacture and use and high production efficiency, it has been widely used in modern industrial and mining enterprises.Porkwork planer machine (hereinafter referred to as wood planer) Is composed of a motor, a knife shaft, a platform and the like, and the machine is driven by a motor to rotate the knife shaft for planing lumber during the operation of the equipment. After the equipment is started, the spindle rotation number reaches 2900 revolutions per minute and the rotation number of the knife shaft reaches 4800 revolutions per minute. Which interacts with the stationary platform panel air gap and causes air flow disturbance to form a resonator (aerodynamic noise), which produces aerodynamic noise with no-load noise of up to 103 dB (A)
